COMBUSTOR, GAS TURBINE - MITSUBISHI HITACHI POWER SYS

Title:

COMBUSTOR, GAS TURBINE

Document Type and Number:

WIPO Patent Application WO/2017/150419

Kind Code:

A1

Abstract:

This combustor (3) comprises: a first cylindrical body (11) that holds a fuel nozzle that extends in the direction of an axial line (Ac), and that has air flowing therethrough toward the downstream side; a second cylindrical body (12) that is connected to the downstream side of the first cylindrical body (11); and an outer cylinder (10) that has an inner peripheral surface that, with an outer peripheral surface of the first cylindrical body (11), defines an air introduction channel (C) that introduces air such that the air reverses course at an upstream end of the first cylindrical body (11) and flows toward the downstream side. The inner peripheral surface has formed therein an outside narrowing surface (17) that, with increasing proximity to the upstream-end side of the first cylindrical body (11), extends toward the inside in the radial direction.
